Patent FR-2294874-A1 (FR)
Title: Hybrid vehicle transmission arrangement - has electronic control of engine, pressure sensor and hydrostatic motor
IPC: B60K17/10
Filed: 1974-12-20
Abstract: The hybrid vehicle drive has a main driving engine, a continuously variable transmission, a device to fix speed and power of the engine, and control gear for the transmission. The transmission consists of an oleopneumatic accumulator with a pressure sensor, joined hydraulically to a hydrostatic variable cylinder motor. The output shaft of this motor is joined mechanically to the transmission output shaft. The motor cylinder is controlled by electrohydraulic means. This, in turn, is controlled by a computer acting on pressure in the reservoir, vehicle speed at the power and speed setting of the engine. These controls are all solid state.

Title: Dispenser for inverted paper bags - has guide plate each side and on top shaped to permit extraction of one bag
IPC: B65H1/02
Filed: 1975-02-11
Abstract: The paper bags are (2) vertical in a magazine (1), with their open ends at the bottom. These fit in the distributor and are removed by a suitable mechanism. To ensure one bag only is dispensed at one time, a guide plate (4, 4') is fitted at each side of the magazine and one (6) on top. The side plates approximate to an elongated Z shape and are fixed in an inclined position (5, 5') to cause each bag to bend forwards (F) when extracted. The top guide plate also has an inclined operating face (7), pushing the bag in the same direction as it rises to contact the plate.

Title: Olefin hydroformylation to straight-chain products - with an organophosphorus-complexed metal hydride catalyst
IPC: C07C45/49
Filed: 1975-02-18
Abstract: The hydroformylation of olefins in which (i) >=2H atoms are attached to the unsatd. C atoms of each active ethylenic gp., (ii) the active ethylenic gps. are not conjugated with other aliphatic unsatn., (iii) halogen or OH, if present, are >=2C atoms away from an active ethylenic gp., (iv) internal active ethylenic gps. are in the cis configuration and (v) no amine gps. are present, is carried out by contacting the olefin with H2 and CO at 25-200 degrees C and 1-1000 atm. in the presence of a catalyst of formula LnMH+X- (where n = 2,3 or 4; M is Ni, Pd or Pt; L is R3P, where R is lower alkyl, =12C aryl or =12C aryloxy; X is PF6, HSO4, CH3COO, CF3COO, SbF6, SbCl6, BF4, SnCl6, PhSO3, CH3SO3 or CF3SO3). The catalyst promotes the formation of linear aldehydes and alcohols at the expense of branched-chain products. Linear alcohols (e.g. decyl alcohol) are useful as intermediates for biodegradable detergents; n-butyraldehyde is an intermediate for 2-ethylhexanol, a plasticiser intermediate.

Title: Automatic boiler burner fuel oil economiser - has flap closing flue when burner does not operate and opening when fuel pump started
IPC: F23L13/02
Filed: 1975-03-03
Abstract: A fuel oil economiser for the burner of a boiler has a damper flap pivotal in the flue about a horizontal axis and carried in bearings at each side of the flue. The flap is connected at one end to a pinion which engages a rack. The pressurised fuel oil from a pump is supplied through an inlet and applies pressure to a piston which moves towards an adjustable stop. The piston is connected to the rack which meshes and is returned to its original position by the action of two coil springs. The flap closes the flue when the burner is not operating, but opens when the fuel oil pump is started.
Patent FR-2310789-A1 (FR)
Title: Degassing liquids, esp. jet fuel - by stripping with inert gas under reduced pressure
IPC: B01D19/00

Patent FR-2317635-A1 (FR)
IPC: G01F23/296
Filed: 1976-07-09
Abstract: In order to establish the level of an interface between two media, such as gas and liquid in a container (4), an acoustic wave (2) is coupled into the container via a sound conductor (3) from outside by means of an acoustic transducer as transmitter (1) which can be a piezoelectric vibrator. Said acoustic wave is transmitted onto the container wall and propagates therein as a sound wave (10). The direction of propagation of the sound wave (10) along the container wall (4) is determined by the direction of incidence of the wave (2), which is at a sloping angle to the container wall (4). With the aid of an electroacoustic transducer as receiver (12), the sound wave (10) transmitted in the wall is coupled out via a sound conductor (11, 13), received and converted into an electrical signal. The signal thus received is input via an amplifier (15) into a measuring unit (17). Depending on the position of the interface with respect to the transmission path (9) of the sound wave, the amplitude of the transmitted signal varies, and from this inferences are drawn on the position of this interface. The invention is applied, for example, in automatic control systems for hydrometallurgical treatment processes in iron and non-ferrous metal smelting plants, and also in the petroleum and foodstuffs industries.
Patent FR-2320251-A1 (FR)
Title: Handling length of material during processing - material in continuously fed but deposited in temporary storage during processing stage then retrieved at faster rate
IPC: B65H20/28
Filed: 1976-08-05
Abstract: The lenth of material is subjected to at least one manufacturing process, which the continuously supplied length of material is placed in a storage. After the interruption, the length of material is removed from the storage and during this retrieval time machines adjoining the storage run at a higher speed than the feeding speed until the storage is empty. The lengths of material is fed to the machine through a slot in the bottom of the storage. During production stoppage one of the production machines is moved in forwards and reverse direction across the length of material in such a way that the length of material is deposited in a zig-zag formation in the storage. When the production is resumed the slot opening in the storage is moved in forwards and in reverse direction at a speed corresponding to the throughput speed of the production machines.

Title: Sheet folding machine bend angle indicator - has two parallel spring loaded sensing rods in contact with sheet during bending
IPC: B21D5/02
Filed: 1976-08-27
Abstract: A folding machine for metal sheets has a block (1) with a pointed tip (13) which is lowered onto the sheet (4) so as to force it into a groove (2) in a bed (3) underneath. Behind the sloping rear face (12) of the block are two parallel rods (5, 6) with pointed tip (A, B) which rest on the sheet as it is being bent, to sense the angle of the sheet during bending. These two rods pass through the upper part of the block, and also carry helical springs (21) around them, also housed piece and a swinging arm (18) respectively, in an upper housing, with a spring (20) acting on the other end of the arm. The angle of this arm is at the same angle as the slope of the sheet being bent.

Patent FR-2396116-A1 (FR)
Title: Prodn. of six-layered floor covering material - with pre-gelling of first plastisol layer to obviate use of paper support
Inventor: PIQUILLOUD PIERRE CHARLES
IPC: D06N3/06
Filed: 1977-06-29
Abstract: A floor covering material is produced which comprises six layers : (1) a cellular plastic e.g. PVC material; (2) a dimensionally stabilising layer of e.g. non-woven glass fibres; (3) a second layer of the plastic material; (4) a further layer of cellular plastic material which is raised in relief; (5) an ink layer; and (6) a transparent, protective layer of e.g. PVC. The novelty resides in the pre-gelling of the first plastisol layer (1) so that a paper support is no longer necessary for the transport of the first soft layer through the curing ovens. Paper normally used for this purpose is expensive, and usually siliconised for use more than once. Further, the removal of the paper support can provide further finishing problems due to irregular surfacing.
